CONCRETE CONSTRUCTION Specification of Letters Patent.

Patented Jan. 25, 1am.

Application filed April 29,1909. Serial No. 492,864.

To all whom it may concern:

Be it known that l, JOHN E. CONZELMAN, a citizen of the United States, residing .at the city of St. Louis, State of Missouri, have invented certain new and useful Improve ments in Concrete Construction, of which the following is a specification, reference behad therein to the accompanying draw lngs.

'This'invention consists in a modification of the concrete structure that forms the subject-matter of my copending application for patent,Serial No. 471,431, filed January 9, 1909.

p In the drawings forming part of this specification in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a plan View showing slabs supported upon a steel column; F ig, 2 is a side elevation of same; and Figs. 3 and 4 are modifications ofthe construction shown in Figs. 1 and 2.

The column 1 is surmounted by a plate 2 upon which flanges 3 of concrete slabs 4 rest.

Said slabs join each other without an intermediate space for the formatlon of a concrete beam, but cut-away parts 5 at each former.

reinforcing bars 7 are located therein, andplastic concrete is poured into sald space, and sets therein, being supported .whlle' corner adjacent a supporting column, unite to form a cruciform space partly over plate 2 and partly with an open bottom, which.

must be temporarily closed with a board or cruciform space from the slabs 4;, and other Reinforcing bars 6 extend into said shown in Fig. 4, a slight departure is made from that depicted in Figs. 1, 2, and 3 in the respect that plate 2 is omitted in the con-. struction, and the space inside'and around the column is filled with concrete.

Having thus described my said invention, what I claim and desire to secure by. Letters Patent is:

1. A concrete construction comprising a plurality of slabs having cut-away portions,

said cut-away portions aplurality of said slabs uniting to form a space, a post, a plate .surmounting said post and underlying said s ace, reinforcing bars projecting from said s abs into said space, and a concrete filler for said space adapted to set integrally with the .edges of said slabs surrounding said space.

2. A concrete construction comprising a plurality of slabs having cut-away portions,

said cut-away portions in a plurality of. said slabs unltmg to form a space, a post, a plate surmounting said post and underlymg said 2' space, reinforcing bars projecting from said slabs into said space, and a concrete fillerfor said space adapted to set integrally'wlth the edges of said slabs surrounding said space,

there being also reinforcing bars which overlap said first-mentioned bars.

3.- A concrete construction...comprising a plurality of slabs havlngcut-away portions,

said cut-away portions in a plurality of said" slabs uniting to form a space, a post, a ophcrete column formed around andwithin said post and underlying said space, reinforcing bars projecting from said slabs into said space and overlapping one another, and a concrete filler for said space adapted to set integrally with the edges of said slabs surrounding said space.

In testimony whereof I have afiixed my signature in presence of two wltnesses.
